Hehe I have so many embarassing bands in my itunes...no joke, I go on really random downloading sprees, so I have some of the weirdest stuff on there. For example:
Spice Girls, Christina Aguiliara (i know that's not spelled right...), N'Sync, Drexy's Midnight Runners, B*Witched (fav. band when I was about 10), TONS of Disney stuff (and I'm talking the old-school animated musical songs), some random Indian stuff (like from the movie Bend It Like Beckham), lots of showtunes, and TONS of 1 hit wonders and 90s songs (I usually find this music after watching some random countdown shows on Vh1...).
As for the stuff I'm not so embarrassed about: The Beatles, The Doors, Led Zepplin, Janis Joplin, Jefferson Airplane, Buffalo Springfield, Jimi Hendrix, and The Kinks.
